🧹 Nitpick comments (8)
website/templates/slack.html (1)
282-312: Consider documenting list/cancel subcommands for reminders and huddlesThe new command docs for
/blt_poll,/blt_remind, and/blt_huddlelook accurate for the basic create flows. Given that the implementation also supports listing and cancelling reminders/huddles, you might optionally add a brief note or extra examples for those subcommands so this page reflects the full feature set.website/tests/test_slack.py (1)
318-603: Slash command tests cover main happy paths and help flows wellThe new tests around
/blt_poll,/blt_remind, and/blt_huddleexercise both help (no‑text) and standard creation paths, and validate the resulting database state (questions/options, reminder status/target, huddle fields and participants, activity logging). The request construction is consistent with existing Slack command tests and should give good regression protection.If you want to tighten them further later, you could factor out the repeated Slack user/mocking setup into small helpers and add one or two negative‑case tests (e.g., too few poll options, invalid time syntax), but that’s optional.
website/admin.py (1)
1001-1006: Default admin registration is sufficient for initial Slack featuresRegistering the SlackPoll/Option/Vote, SlackReminder, SlackHuddle, and SlackHuddleParticipant models with the default admin is a good starting point. If usage grows, you might later add list filters (e.g., by status/workspace) for easier operations, but nothing is required now.
website/management/commands/process_slack_reminders_and_huddles.py (2)
123-125: Queryingworkspace_namewith a workspace ID appears intentional but is confusing.The field name
workspace_nameis used to store the Slack team/workspace ID (not the human-readable name). This matches existing patterns inslack_handlers.pybut the naming is misleading. Consider renaming the field in a future migration for clarity.
215-221: Redundantdry_runcheck inside the non-dry-run branch.Line 218 checks
not options["dry_run"], but this code is already inside theelseblock (line 215) that only executes whendry_runisFalse. The condition is always true and can be simplified.else: ok_count = 0 ws_token = self._token_for_workspace(huddle.workspace_id, token) - if not ws_token and not options["dry_run"]: + if not ws_token: huddle.reminder_sent = True # avoid infinite loop; no token to send huddle.save(update_fields=["reminder_sent"]) continuewebsite/views/slack_handlers.py (3)
92-104: Sequential API calls in_validate_users_existcould be slow for many users.Each user ID triggers a separate Slack API call. For huddles with many participants, this adds latency. Consider batching if Slack's API supports it, or adding a reasonable limit on participant count.
3169-3192: Poll creation is not transactional with Slack message posting.If
chat_postMessagefails after the poll is created in the database, an orphaned poll (withmessage_ts=None) remains. Consider wrapping the DB operations in a transaction or adding cleanup for polls withoutmessage_ts.
3602-3631: Same transactional concern as polls—orphaned huddles if Slack API fails.If
chat_postMessagefails after huddle creation, an orphaned record withmessage_ts=Noneremains. Consider consistent cleanup or transactional handling across all commands.

20-24: Slack scheduler hook integrates cleanly with existing 10‑minute tasksThe new
process_slack_reminders_and_huddlescall follows the same error‑isolation pattern ascron_send_reminders, so a Slack‑specific failure won’t break the entire scheduled run while still being logged with full traceback. No changes needed here.website/tests/test_slack_blocks.py (1)
1-46: Block‑builder tests provide good coverage of key UX elementsThese tests hit the critical behaviors for polls (question/options plus non‑zero bar rendering) and huddles (header plus action buttons). The assertions on the JSON‑serialized blocks are straightforward and should be stable as long as the bar character and action block structure remain part of the design.
website/admin.py (1)
80-87: Slack models correctly wired into adminThe additional imports for the Slack poll/reminder/huddle models are correct and match the model names and relationships in
website.models. No issues here.website/migrations/0264_slackhuddle_slackpoll_slackpolloption_slackreminder_and_more.py (1)
13-204: Migration schema matches Slack model definitions and indexing needsThe migration cleanly defines all six Slack models with the expected fields, status choices, uniqueness constraints, and multi‑column indexes. It’s aligned with the model definitions in
website.modelsand should support the query patterns used by the handlers and scheduler.website/models.py (1)
3650-3880: Slack poll/reminder/huddle models are well‑structured and indexedThe new Slack models are coherent and match the intended workflows:
- Polls:
SlackPoll,SlackPollOption, andSlackPollVotemodel questions, options, and per‑option votes with appropriate uniqueness and indexing, plus an explicitclose_pollhelper.- Reminders:
SlackRemindercaptures target, timing, and status with helper methods for sent/failed/cancelled, and indexes tuned for “due pending reminders” queries.- Huddles:
SlackHuddleandSlackHuddleParticipantrepresent scheduled meetings and participant responses, with small guard‑railed state‑transition helpers and a set‑basedVALID_RESPONSESfor fast validation.The structure looks solid for the scheduler and Slack command handlers; I don’t see any correctness issues here.
website/tests/test_slack_scheduler.py (1)
19-107: Scheduler dry‑run tests exercise key reminder and huddle transitionsThese tests set up realistic SlackIntegration/Organization records, patch outbound HTTP, and verify the crucial behaviors of
process_slack_reminders_and_huddlesin dry‑run mode: due reminders are marked sent, upcoming huddles get their pre‑notification flag set, and past huddles move tostarted. This should give good coverage of the main state transitions without relying on actual Slack API calls.website/management/commands/process_slack_reminders_and_huddles.py (2)
1-16: LGTM on imports and constants.The imports are appropriate for the task. Constants for retry logic (
MAX_RETRIES,BASE_BACKOFF_SECONDS) are well-defined.
127-181: Transaction holds locks during network I/O—acceptable withskip_lockedbut worth monitoring.The design processes reminders atomically within a single transaction, including Slack API calls. With
skip_locked=True, concurrent runs won't deadlock. Monitor for lock contention if batch sizes grow or Slack latency increases.website/views/slack_handlers.py (6)
327-338: LGTM on action routing.The new action handlers follow the established
startswith()pattern and integrate cleanly with the existing dispatch logic.
1355-1380: Good granular error handling for Slack API failures.The specific error code handling (
ratelimited,channel_not_found,invalid_auth, etc.) with appropriate HTTP status codes improves debuggability and user experience.
3278-3413: LGTM on reminder command handler.Good input parsing with multiple format support, user validation before creation, and defensive error handling for channel confirmation posting.
3850-3880: LGTM on poll close handler.Proper authorization check (only creator can close) and status validation before closing.
3718-3778: Good use of annotation for participant counts.Using
.annotate(participants_count=Count("participants"))avoids N+1 queries when listing huddles.
3216-3226: No action required. Thevote_countproperty exists on theSlackPollOptionmodel and is properly implemented as@property def vote_count(self): return self.votes.count(). The fallback in line 3220 is safe and will work correctly as a defensive programming pattern when the annotation is unavailable.Likely an incorrect or invalid review comment.

3724-3742: Consider the unique constraint for single-vote enforcement.The
unique_together = ["poll", "voter_id", "option"]constraint allows users to vote for multiple options (one vote per option). However, the PR objectives mention "single-vote enforcement." This constraint only prevents duplicate votes on the same option, not multiple votes across different options.If the intention is to enforce strictly one vote per user per poll (regardless of
allow_multiple_votes), the constraint should be["poll", "voter_id"]. Otherwise, the application logic in the handler must enforce single-vote behavior whenallow_multiple_votes=False.Based on past review comments, this constraint design has been previously discussed. Please verify that the handler logic correctly enforces single-vote behavior when
allow_multiple_votes=False.website/views/slack_handlers.py (3)
3571-3573: Wall-clock time parsing uses UTC, not user's local timezone.When a user says "at 3:00 PM", they likely mean their local time, but
timezone.now()returns UTC. This was flagged in a previous review. Consider documenting that times are in UTC, or fetching the user's timezone from their Slack profile.
3355-3367: Add validation for non-positive time amounts.The regex allows zero or negative values to be entered, which would create confusing or invalid reminders. This was flagged in a previous review.
amount = int(time_match.group(1)) unit = time_match.group(2) + + if amount <= 0: + return JsonResponse( + { + "response_type": "ephemeral", + "text": "❌ Time amount must be greater than 0.", + } + ) # Calculate remind_at time
3548-3555: Add validation for non-positive time amounts in huddle scheduling.The relative time parser allows zero or negative values. This was flagged in a previous review.

🧹 Nitpick comments (3)
website/views/slack_handlers.py (3)
65-69: Overly broad exception handling hides potential bugs.Catching all exceptions and silently falling back to
time.time()can mask unexpected errors. Consider logging a warning so issues are observable.try: ts = int(dt.timestamp()) - except Exception: - # Fallback to current time if something odd happens + except (OSError, OverflowError, ValueError) as e: + logger.warning("Failed to convert datetime %s to timestamp: %s", dt, e) ts = int(time.time())
3169-3178: Poll and options creation should be wrapped in a transaction.If option creation fails partway through the loop, the poll will exist with incomplete options. Use
transaction.atomic()to ensure atomicity.+from django.db import transaction + ... - # Create poll in database - poll = SlackPoll.objects.create( - creator_id=user_id, workspace_id=team_id, channel_id=channel_id, question=question, status="active" - ) - - # Create poll options - for idx, option_text in enumerate(options): - # Sanitize user input to prevent markdown injection - sanitized_option_text = re.sub(r"([*_~`>])", r"\\\1", option_text) - SlackPollOption.objects.create(poll=poll, option_text=sanitized_option_text, option_number=idx) + # Create poll in database atomically + with transaction.atomic(): + poll = SlackPoll.objects.create( + creator_id=user_id, workspace_id=team_id, channel_id=channel_id, question=question, status="active" + ) + + # Create poll options + for idx, option_text in enumerate(options): + # Sanitize user input to prevent markdown injection + sanitized_option_text = re.sub(r"([*_~`>])", r"\\\1", option_text) + SlackPollOption.objects.create(poll=poll, option_text=sanitized_option_text, option_number=idx)

20-24: LGTM!The integration of the new Slack command follows the same error-handling pattern as the existing
cron_send_reminderscommand, logging errors without propagating exceptions to the outer handler.website/tests/test_slack.py (4)
2-2: LGTM!The
urllib.parseimport is used later in the test file (line 489) for encoding POST data.
319-416: LGTM!The poll command tests follow established patterns from earlier in the file. They correctly mock Slack API interactions and verify both database state (poll creation, options count, status) and activity logging.
419-520: LGTM!The reminder command tests verify both help and creation flows, with appropriate mocking of Slack API and assertions on database state (message, status, target_id) and activity logging.
523-619: LGTM!The huddle command tests cover help responses and creation, including participant tracking. The tests verify database state (title, description, status, participant count) and activity logging as expected.
website/models.py (6)
29-29: LGTM!The
escapeimport is correctly used later in the file at line 3787 in theSlackReminder.mark_as_failedmethod for sanitizing error messages.
3650-3687: LGTM!The
SlackPollmodel is well-structured with appropriate fields, indexes, and theclose_poll()helper method for status transitions.
3689-3722: LGTM!The custom
QuerySetwithwith_vote_count()annotation and thevote_countproperty provide efficient vote counting while avoiding N+1 queries when used correctly.
3744-3797: LGTM!The
SlackRemindermodel includes appropriate status transitions, helper methods (mark_as_sent,mark_as_failed,cancel), and usesescape()at line 3787 for safely storing error messages.
3799-3860: LGTM!The
SlackHuddlemodel provides status lifecycle methods (cancel,start,complete) with appropriate atomic updates usingfilter().update()to handle concurrency.
3862-3897: LGTM!The
SlackHuddleParticipantmodel correctly usesuser_id(notslack_id) and provides anupdate_responsemethod with proper validation againstVALID_RESPONSES.website/tests/test_slack_scheduler.py (4)
18-28: LGTM!The test setup creates appropriate fixtures (Organization, Integration, SlackIntegration) to support the Slack scheduler tests.
29-53: LGTM!The test verifies that a due user reminder is marked as "sent" in dry-run mode. The mock setup for Slack API responses is appropriate.
54-71: LGTM!The test verifies dry-run behavior for channel reminders, including the assertion that no actual API calls are made (
mock_post.assert_not_called()).
72-103: LGTM!The test verifies huddle pre-notifications and status transitions: upcoming huddles get
reminder_sent=Trueand past huddles transition tostatus="started", all in dry-run mode without actual API calls.website/management/commands/process_slack_reminders_and_huddles.py (8)
19-24: LGTM!Token sanitization removes carriage returns and line feeds to prevent header injection attacks.
27-55: LGTM!The function correctly checks for HTTP 429 (rate limit) before attempting JSON parsing, and returns the
Retry-Aftervalue for exponential backoff handling. The logic distinguishes between user IDs (requiring DM channel resolution) and channel IDs (used directly).
58-83: LGTM!The function correctly checks for rate limiting (429) before parsing JSON and returns the retry delay. Thread support via
thread_tsis also properly implemented.
86-102: LGTM!The helper functions for parsing retry counts and formatting error messages support the exponential backoff strategy.
104-127: LGTM!The command structure with configurable arguments (window-minutes, batch-size, dry-run) and per-workspace token resolution is well-designed.
128-188: LGTM!The reminder processing correctly:
- Uses
select_for_update(skip_locked=True)for concurrent safety- Resolves per-workspace tokens
- Escapes message content for Slack (replacing &, <, > with HTML entities as per Slack's requirements)
- Implements exponential backoff capped at MAX_RETRIES with support for Slack's Retry-After header
- Handles dry-run mode appropriately
189-242: LGTM!The huddle processing correctly:
- Uses
prefetch_related("participants")to avoid N+1 queries- Correctly accesses
user_idfrom participants (notslack_id)- Escapes title content for Slack message formatting
- Sends pre-notifications to both participants and channels
- Respects dry-run mode
243-255: LGTM!Huddle status transitions use
select_for_update(skip_locked=True)for safe concurrent processing and correctly mark scheduled huddles as "started" when their time arrives.website/views/slack_handlers.py (7)
3832-3838: Race condition fix looks correct.Using
get_or_createwithdefaultsis the right approach to atomically prevent duplicate votes. The unique constraint on(poll, voter_id)at the model level would provide additional protection.
3927-3931: Action ID parsing fix is correct.The logic now correctly maps
response="accepted"toaction_verb="accept"(and similarly for decline), matching the actual action IDs used inbuild_huddle_blocks.
3674-3675: Single query for participants is acceptable here.While
prefetch_relatedcould be used for batch operations, fetchinghuddle.participants.all()for a single huddle display is already efficient (one query). This is fine as-is.
3730-3734: Good use of annotation to avoid N+1 queries.Using
.annotate(participants_count=Count("participants"))is the right approach to efficiently get participant counts without additional queries per huddle.
1356-1380: Comprehensive Slack API error handling.Good coverage of common Slack API errors (rate limiting, auth issues, channel problems) with appropriate HTTP status codes and user-friendly messages.
3217-3228: Good vote counting optimization with annotation.Using
.annotate(votes_count=Count("votes"))avoids N+1 queries. The bar length calculation withmax(1, math.ceil(...))for non-zero votes ensures small percentages remain visible.
3855-3888: Consistent permission checking pattern across handlers.The

Here's my assessment: ✅ Implementation Completeness: ~85%The PR successfully implements the core requirements from issue #2183, but there are several critical bugs, missing edge cases, and test coverage gaps that should be addressed before merge. 🐛 Critical Bugs1. Poll Single-Vote Enforcement is BrokenLocation: The Fix needed: # In SlackPollVote model
class Meta:
unique_together = ["poll", "voter_id"] # Prevent any duplicate votes per poll
# OR implement validation in handle_poll_vote to check existing votesIn # Before creating vote, check if user already voted
existing_vote = SlackPollVote.objects.filter(poll=poll, voter_id=user_id).first()

else:
# Update vote or return error
return JsonResponse({"response_type": "ephemeral", "text": "❌ You've already voted. Close and reopen the poll to change your vote."})2. Unused Model FieldsThe ❌ Missing Functionality1. No Edit/Update Capabilities
2. Limited Huddle Time ParsingReminders support "in X days" but huddles only support "in X hours" or "at HH:MM AM/PM". Should be consistent. 3. No Completion Tracking for HuddlesThe background processor marks huddles as "started" but never marks them as "completed" after 4. No Cross-Channel Reminder/Huddle Listing
5. No Data Cleanup/ArchivalOld polls, reminders, and huddles will accumulate indefinitely. Need a cleanup strategy or auto-archival.

191-193: Avoidcache.clear()in tests; delete only the rate-limit keys you setUsing
cache.clear()in these tests is still a global operation and can interfere with other tests that rely on cache state (especially under parallel execution). Since the rate limiter uses a specific key pattern, you can reset only the keys relevant to these tests.Example: clear only the huddle rate-limit key
- # Clear entire cache to avoid rate-limit interference - cache.clear() + # Clear only the rate-limit key used by /blt_huddle for this user + cache.delete(f"slack_rl:huddle:{self.creator_id}")Apply a similar pattern in the other tests that currently call

3140-3262: Poll creation & rendering are robust; consider making creation+post fully atomicPositives in
handle_poll_command/build_poll_blocks:
- Strong input hygiene: quoted parsing, whitespace normalization, truncation, deduplication, and markdown escaping for both question and options.
- Option count limits enforced (2–10, capped by
MAX_POLL_OPTIONS).- Block building uses
annotate(votes_count=Count("votes"))to avoid N+1 queries and a progress bar that handles small non-zero percentages gracefully.- Single-vote semantics enforced in
SlackPollVote(DB uniqueness) andhandle_poll_vote.One improvement for data hygiene: if
chat_postMessagefails, aSlackPollis already created withmessage_ts=None. The vote/close/reopen handlers now guard against missingmessage_ts, so this no longer crashes, but it still leaves orphaned polls that never made it to Slack.You could mirror the huddle pattern and wrap poll creation and posting in a single transaction so failed posts fully roll back.

3812-3865: Huddle time parsing works but lacks bounds and detailed validationThe
/blt_huddleedit and create flows correctly support both “in N minutes/hours/days” and “at HH:MM [AM/PM]” formats, and you’ve added a nice “time has already passed today” guard for theatcase. However:
- The “in” paths don’t enforce
amount > 0or any upper bound, unlike reminders. Extremely large values (in 999999999 days) can overflowdatetimearithmetic and fall into the generic error handler.- The
atparsing for both create and edit paths doesn’t validate hour/minute ranges; invalid inputs likeat 25:99will reachnow.replace()and raiseValueError, again surfacing only as a generic error.If you want huddles to be as robust as reminders, consider:
- Applying a similar “> 0 and ≤ 1 year” cap for
inamounts.- Validating hour/minute ranges (and AM/PM) before calling
replace, and returning a specific ephemeral error for invalid times.Illustrative validation enhancements for the
atpath- at_match = re.search(r"at\s+(\d{1,2}):(\d{2})\s*(AM|PM)?", remainder, re.IGNORECASE) + at_match = re.search(r"at\s+(\d{1,2}):(\d{2})\s*(AM|PM)?", remainder, re.IGNORECASE) if at_match: hour = int(at_match.group(1)) minute = int(at_match.group(2)) am_pm = at_match.group(3) - if am_pm: - if am_pm.upper() == "PM" and hour < 12: - hour += 12 - elif am_pm.upper() == "AM" and hour == 12: - hour = 0 + # Validate ranges first + if minute < 0 or minute > 59: + return JsonResponse( + { + "response_type": "ephemeral", + "text": "❌ That time isn't valid.

inamounts as you did for reminders.Also applies to: 3914-3963
3364-3653: Refactor slashsnoozeto reuse_compute_remind_atvalidation and avoid logic duplicationThe reminder implementation is well-structured overall:
_compute_remind_atcentralizes amount/unit validation and is correctly reused by the create and edit paths. However, the slashsnoozesubcommand duplicates this validation and timedelta construction instead of calling the helper. The snooze logic reimplements the identical bounds (525600 minutes, 8760 hours, 365 days) and error messages, making the two paths prone to drift.Refactoring the snooze subcommand to reuse
_compute_remind_at(or a shared helper wrapping it with snooze-specific response messages) would eliminate duplication and guarantee consistent validation across all reminder modification paths.

26-271: Strong, targeted coverage for poll/reminder/huddle interactionsThese tests exercise the main happy paths and the key edge cases called out in earlier reviews (duplicate votes, closed polls, invalid IDs, already-cancelled/sent reminders, snooze permissions, huddle accept/decline, cancel-after-start, invalid mentions, and past-time validation). They line up well with the handler contracts in
website/views/slack_handlers.pyand materially reduce regression risk around the new workflows.Also applies to: 308-440

4428-4469: Reminder snooze button handler correctly addresses the earlier race conditions
handle_reminder_snoozenow:
- Uses
transaction.atomic()+select_for_update(skip_locked=True)on the reminder row.- Re-checks
status == "pending"under the lock.- Enforces that only the creator or the target can snooze.
- Updates only
remind_atviasave(update_fields=["remind_at"]).This design avoids both of the previously reported races: no stale overwrite of
statusfromsentback topending, and no “snooze appears to succeed but background worker already sent it” inconsistency.
54-125: Helper utilities for channels, rate limiting, dates, and user validation look solid
_ensure_bot_in_channel,_rate_limited,_slack_date,_get_allowed_channels, and_validate_users_existare cohesive and reused consistently across polls/reminders/huddles. They centralize Slack-specific concerns (membership, local-time tokens, channel allowlists, and user existence) and keep the command handlers focused on business logic. The_slack_dateimplementation correctly uses the<!date^...>token format, which is Slack's official approach for viewer-local time display.
1380-1408: SlackApiError handling now preserves error codes correctlyThe new pattern for extracting
errfromSlackApiError(avoiding(e.response or {})) insend_dm,handle_poll_vote,handle_poll_close, andhandle_poll_reopenfixes the earlier issue whereSlackResponse.__bool__caused real error payloads to be dropped. This restores the specific branching forratelimited,channel_not_found,not_in_channel,invalid_auth, etc., and gives users much clearer feedback while keeping vote/close/reopen operations idempotent.Verify against the current slack-sdk docs that `SlackApiError.response` continues to expose a mapping interface with `.get("error")` so this pattern remains future-proof.Also applies to: 4245-4254, 4496-4504
348-363: Action and command wiring for polls/reminders/huddles is coherentThe new
block_actionsbranches correctly route interactive component triggers to dedicated handlers, and they respect workspace-specific clients derived fromSlackIntegration. This isolates the new features cleanly from existing commands and keeps multi-workspace token handling consistent.
3980-4005: Huddle creation, listing, and block building are well-structuredThe huddle flow is nicely put together:
- Creation is wrapped in
transaction.atomic()with participants and Slack message posting inside the transaction, andmessage_tssaved only after a successfulchat_postMessage, avoiding orphaned DB rows.build_huddle_blocksproduces a clear summary (description, when, duration, status, organizer) and aggregates participant responses into readable sections.list_channel_huddlescorrectly supports both per-channel and cross-channel (scope_all) listings withparticipants_countannotations and DM delivery viasend_dm.This structure matches the tests in
SlackInteractionHandlerTestsand provides a solid base for future "edit" extensions (e.g., changing description or participants).Verify block kit size constraints for real workloads: Slack limits messages to 50 blocks, and section block text is limited to 3000 characters while markdown blocks are limited to 12000 characters. Ensure huddle lists and block builders account for these limits, especially when displaying huddles with long descriptions or many participants.

3800-3865: Huddle time parsing still lacks bounds and hour/minute validation (edge-case UX issues)The
/blt_huddleedit and create flows both:
- Accept
"in N <minutes|hours|days>"without checkingN > 0or enforcing an upper bound (unlike reminders, which cap at ~1 year via_compute_remind_at).- For
"at HH:MM [AM/PM]", directly calltimezone.now().replace(hour=hour, minute=minute, ...)without validating thathour/minuteare within valid ranges.This means inputs like
in 99999999 daysorat 25:99can raiseOverflowError/ValueErrorand fall through to the generic “❌ An error occurred. Please try again.” handler instead of a clear validation error, and “at 3:00 PM” is interpreted as 15:00 UTC rather than the user’s local wall‑clock time.Suggested direction (non‑blocking but worth tightening):
- Mirror
_compute_remind_at’s semantics for huddles: require amount > 0 and cap minutes/hours/days to something reasonable (e.g., 1 year).- Add explicit hour/minute validation for the
"at"form (e.g., 0–23 for 24h or 1–12 with AM/PM, minute 0–59) and return a targeted error instead of relying onreplace()raising.- Consider using
timezone.localtime()or a user/workspace timezone when interpreting"at HH:MM"so wall‑clock semantics are clearer.[Suggesting as a follow-up since earlier reviews already touched on this area.]

- Poll question and options (
handle_poll_command),- Reminder messages (create/edit/list),
- Huddle titles/descriptions (
handle_huddle_command),- Various mrkdwn sections that interpolate user text.
Given the implementation, this function is really an HTML/entity escape to prevent
<@user>/<http://...>/&artifacts, not a full Slack markdown escape (it doesn’t touch*,_,~,`, etc.). That’s fine security‑wise, since the critical thing is neutralizing</>and&, but the name/docstring overstate what it does.I’d suggest either:
- Renaming/doc‑tweaking it to something like
escape_slack_entities/ “Escape &, <, > for safe inclusion in Slack text/mrkdwn”, or- Extending it to also backslash‑escape Slack markdown control characters if you want truly literal rendering in mrkdwn fields.
This is non‑blocking, but clarifying intent here will make future uses less error‑prone.

3656-3735: Reminder list actions: “Cancel” vs “Snooze” semantics for reminders assigned by others
list_user_reminders(..., scope_all=True)shows both “Cancel” and “Snooze 1h” buttons for:
- reminders you created, and
- reminders created by someone else but targeted to you.
Behavior now is:
handle_reminder_snoozecorrectly allows either the creator or the target to snooze (good).handle_reminder_cancelonly allows the creator to cancel (also good), but still renders a Cancel button for non‑creators, producing a “❌ Only the reminder creator can cancel it.” error when clicked.So the UI suggests an action that is guaranteed to fail for reminders where you’re only the recipient.
Consider one of:
- Hiding the Cancel button in
list_user_reminderswhenscope_all=Trueandreminder.creator_id != user_id, or- Keeping the button but tweaking the label/help text so it’s clear only the creator can cancel.
The logic itself is correct; this is mostly a UX clean‑up.

4201-4265: Poll and huddle interaction handlers now handle missingmessage_tsand Slack failures gracefullyThe updated handlers for polls and huddles are robust:

chat_updatecalls with amessage_ts is Nonecheck and return a success message even when the Slack message can't be refreshed, logging details for operators.handle_huddle_command+handle_huddle_response+handle_huddle_cancel:
- Create huddles and post the initial message inside a transaction so there are no orphaned DB rows when
chat_postMessagefails.- In response/cancel flows, they re-post a message if
message_tsis missing and otherwise update in place, with broadtry/exceptso user actions don't fail hard due to Slack API issues.These changes resolve the earlier issues around orphaned huddles/polls and misleading error messages after a successful DB state change.

4318-4348: Reminder cancellation now correctly uses the boolean return from.cancel()
handle_reminder_cancelchecks creator permissions, ensures status ispending, and then relies onreminder.cancel()’s boolean result to distinguish between a successful cancel and a concurrent status change. The fallback “no longer pending” response correctly covers the race where the scheduler or another action updated the status between load and cancel.
4351-4402: Huddle response handler is correct and fixes the action_id suffix bug
- Mapping
response("accepted"/"declined") to"accept"/"decline"for theaction_idprefix fixes the previoushuddle_{response}_parsing bug.- You correctly guard on
huddle.status == "scheduled"to prevent responses on completed/cancelled huddles.SlackHuddleParticipant.get_or_create+update_response(response)implements idempotent updates, and the subsequent message update is robust: it either posts a fresh message whenmessage_tsis missing or callschat_updateotherwise, with guarded logging on failures.This closes the earlier correctness issue around parsing and keeps participant state consistent.
4405-4452: Interactive reminder snooze now handles scheduler races and avoids stale writes
- Using
transaction.atomic()plusselect_for_update(skip_locked=True)and a fresh status check onstatus == "pending"prevents the race conditions previously noted withprocess_slack_reminders_and_huddles.- Allowing snooze when the acting user is either the creator or the target aligns behavior with what the “Snooze 1h” button affords in
list_user_reminders.- Updating only
remind_atviasave(update_fields=["remind_at"])ensures you don’t accidentally revert concurrent status changes to or from"sent"/"failed".This addresses the prior bug reports around snooze silently failing or corrupting status.
4516-4571: Huddle cancellation correctly respects concurrency and Slack update issues
- Cancellation is restricted to the organizer and to huddles in
scheduledstate.- Using
huddle.cancel()’s boolean return prevents false‑positive successes when the status changed concurrently (e.g., tostarted), and you surface a clear “no longer scheduled” message when the conditional update doesn’t apply.- The follow‑up Slack message handling mirrors edit/response flows: guarded against missing
message_ts, tolerant ofchat_postMessage/chat_updatefailures, and always returning a success to the user once the DB state has moved tocancelled.This is a solid, race‑aware implementation of the cancel flow.
3140-3361: Poll creation, sanitization, and block building are generally robust
- Channel restriction + per‑user rate limiting are implemented cleanly.
- Parsing
"Question" "Option 1" ...with deduplication, whitespace normalization, length caps, and 2–10 option enforcement matches the documented behavior.- DB writes are simple and
build_poll_blocksuses annotated vote counts with a well‑behaved progress bar and creator‑only Close/Reopen controls.- Guarding
poll.message_ts is Nonein downstream handlers (vote/close/reopen) mitigates orphan‑record edge cases whenchat_postMessagefails.One thing to tighten:
escape_slack_markdowncurrently only escapes&,<, and>, while its docstring claims to escape “Slack's markdown‑like characters”. If the intent is to keep poll questions/options purely textual (no bold/italic/strikethrough), consider either extending the helper to also backslash‑escape*,_,~,`, etc., or updating the docstring and comments so it’s clear that markdown styling is intentionally allowed here.What are the recommended escaping rules for user-provided text in Slack Block Kit messages to prevent unintended markdown formatting?
3725-4146: Huddle command covers the main flows but needs stronger time input validationGood aspects:
- Channel restriction + per‑user rate limiting mirror the poll/reminder behavior.
listand edit flows reuse the same handler andlist_channel_huddlespaginates correctly, with participant counts via annotation.- Creation sanitizes
titleanddescriptionwithescape_slack_markdown, validates participants via_validate_users_exist, and wrapsSlackHuddle+SlackHuddleParticipantcreation andchat_postMessagein a singletransaction.atomic()block, avoiding orphaned huddles on Slack failures.- Edit flow supports both relative (“in X minutes/hours/days”) and wall‑clock (“at HH:MM [AM/PM]”) rescheduling and rewrites the Slack message or posts a new one if
message_tswas missing.Two validation gaps remain:
Missing hour/minute range checks for
"at HH:MM"(edit + create)
- Inputs like
at 25:99orat 13:00 PMwill pass the regex but causetimezone.now().replace(hour=..., minute=...)to raiseValueError. This bubbles to the outerexcept Exceptionand returns a generic “An error occurred” instead of a clear “invalid time” message.- Recommend validating
minute in 0..59and hour ranges before calling.replace():
- With AM/PM: hour in 1..12, then map to 0–23.
- Without AM/PM: hour in 0..23.
No upper bounds or positivity checks for
"in N <unit>"in huddles
- Unlike reminders, huddles accept any non‑negative integer via regex and directly compute
now + timedelta(...). Extremely large values riskOverflowErrorand there’s no explicit “too long” validation oramount > 0check.- For consistency and safety, consider reusing
_compute_remind_ator a sibling helper for huddles (possibly with different copy in the error messages) so you get:
amount > 0enforced.- Reasonable upper caps (e.g., up to 1 year).
- Shared behavior between create and edit.
Addressing these keeps errors user‑friendly and prevents noisy log entries from simple invalid inputs.
How does Python's `datetime.replace` behave when given out-of-range hour or minute values (e.g., 25:99), and what exception type is raised?

3364-3723: Reminder time computation and flows are much cleaner; only minor nits leftPositives:
_compute_remind_atcentralizes validation (amount > 0, 1‑year caps per unit, invalid unit handling) and is correctly reused in create, edit, and slash‑snooze branches.- Creation, edit, and snooze all now sanitize messages via
escape_slack_markdownbefore persistence, aligning with how messages are later rendered in blocks/DMs.- Slash snooze uses
transaction.atomic()+select_for_update(skip_locked=True)andsave(update_fields=["remind_at"]), which addresses the races with the background scheduler that were previously called out.list_user_reminders’ pagination and the “scope_all” behavior (including reminders assigned to you) are clear, and the button wiring for Cancel/Snooze matches the handlers.Minor issues / suggestions:
handle_reminder_command’s docstring still says “/remind” even though the actual command is/blt_remind; worth updating to prevent confusion for future maintainers.- In
list_user_reminders, the “Snooze 1h” button is shown for all reminders in scope; the interactive handler now correctly permits snooze when the acting user is either creator or target, which is good. If you expect many cross‑assigned reminders, you might consider reflecting this in the text (e.g., clarifying that both creator and assignee can snooze) but it’s not required from a correctness standpoint.

54-57: Helpers for rate limiting, channel restriction, and Slack dates look solidThe shared helpers (
_rate_limited,_get_allowed_channels,_slack_date,_ensure_bot_in_channel,_validate_users_exist) are cohesive and used consistently (e.g., in/statsand sweep reports). The semantics and error‑swallowing in_ensure_bot_in_channeland_validate_users_existare appropriate for best‑effort behavior, and_rate_limited’s simple per‑user/command cache key is fine for this scope.Also applies to: 69-75, 78-92, 95-110, 113-125, 3011-3013
348-363: Block action routing for polls, reminders, and huddles is consistentThe new
action_idrouting inslack_eventsmatches the IDs produced bybuild_poll_blocks,list_user_reminders, andbuild_huddle_blocks(vote/close/reopen/cancel/snooze/accept/decline/cancel). This keeps the interaction surface coherent and avoids magic strings scattered elsewhere.
1237-1250: Slash command wiring for/blt_poll,/blt_remind,/blt_huddleis correctCommand dispatch passes the right arguments (
workspace_client,user_id,team_id,channel_id,text,activity) into the respective handlers. This keeps logging and per‑workspace token resolution centralized inslack_commands.
4177-4246: Poll voting path is concurrency-safe and user-friendly
- Fetching
SlackPollOptionviaselect_related("poll")avoids extra queries.- Status check on
poll.statusbefore voting enforces “closed polls cannot be voted on”.SlackPollVote.objects.get_or_create(..., defaults={"option": option})plus catchingIntegrityErrorcombined with the model’sunique_together = ["poll", "voter_id"]gives a solid single‑vote guarantee even under concurrent requests.poll.message_ts is Noneis handled gracefully with a warning and a success message that explains the results weren’t refreshed.SlackApiErrorfromchat_updateno longer tears down the request: all errors are logged, and the user always receives confirmation that their vote is recorded, with a softer message specifically for channel membership issues.All of this matches the desired behavior and resolves the earlier race/UX concerns around voting.
4249-4315: Poll closing flow correctly persists state and softens Slack update failures
- Only the creator can close the poll; attempts by others or on non‑active polls return clear ephemerals.
- DB status transition uses
poll.close_poll(), and message updates are skipped with an explicit user message whenmessage_tsis missing (avoiding the previous crash).- On
SlackApiError, you now log the error, special‑casechannel_not_found/not_in_channelwith a helpful explanation, and otherwise return “✅ Poll closed, but …” instead of a generic failure even though the DB state changed.This keeps poll state authoritative in the DB while giving users accurate feedback about Slack UI updates.
4455-4513: Poll reopen mirrors close semantics and handles missing message_ts safely
- Restricting reopen to the creator and status
"closed"is correct.- The
message_ts is Noneguard returns a success message explaining the UI couldn’t be refreshed, avoiding the orphan‑record crash highlighted earlier.SlackApiErrorhandling matches the close handler: channel membership errors yield a tailored success‑with‑warning response; other errors are logged while still confirming the poll was reopened.This keeps DB and Slack state as consistent as possible without misleading the user.
1381-1408: Improved SlackApiError handling with explicit null checksThe switch from
(e.response or {})to explicitresp = getattr(e, "response", None)and checking for.getis safer and more defensive. SlackResponse supports.get()for retrieving error codes, and granular branching onratelimited,channel_not_found, auth errors, and DM-specific failures provides good UX.

Looks good to me all changes are resolved and works as expected.

@coderabbitai Please conduct a checking for the following issues: Dry-run mutations: Does process_slack_reminders_and_huddles.py's --dry-run flag still mutate database state (marking reminders as sent, updating huddle statuses)? |

I've conducted a thorough investigation of all 11 issues. Here's my detailed analysis: 🔴 Critical Issues Found (Must Fix)1. ✅ Dry-run mutations - CONFIRMED BUGLocation: The # Lines 203-206 (reminders)
if options["dry_run"]:
sent, retry_after = True, None
else:
sent, retry_after = _send_slack_message(ws_token, target, msg)
# Line 209
if sent:
reminder.status = "sent" # ← Mutates even in dry-run!
reminder.sent_at = timezone.now()
reminder.error_message = ""# Lines 284-287 (huddles)
if options["dry_run"]:
logger.info("DRY-RUN huddle=%s notify %d participants", huddle.id, len(participants))
huddle.reminder_sent = True # ← Mutates in dry-run!
huddle.save(update_fields=["reminder_sent"])Fix: Wrap all 2. ✅ Transaction locking with network calls - CONFIRMED BUGLocation: The code holds database locks while making Slack API calls: with transaction.atomic(): # ← Lock acquired
qs = SlackReminder.objects.select_for_update(skip_locked=True)...
for reminder in reminders:
# Inside transaction, making network calls:
exists, retry_after_exists = _user_exists(ws_token, reminder.target_id) # ← Network call!
sent, retry_after = _send_slack_message(ws_token, target, msg) # ← Network call!
reminder.save() # Still holding lockImpact: Database locks held for seconds while waiting for Slack API responses. Under load, this will cause lock contention and timeouts. Fix: Move network calls outside
3. ✅ Unbounded retry loops - CONFIRMED BUGLocation: Retrying reminders push if next_retries <= MAX_RETRIES:
delay_seconds = min(BASE_BACKOFF_SECONDS * (2 ** (next_retries - 1)), 60 * 60)
reminder.remind_at = timezone.now() + timedelta(seconds=delay_seconds) # ← Keeps pushing forward!The cleanup command filters by # cleanup_slack_records.py line 29
reminders_qs = SlackReminder.objects.filter(
status__in=["sent", "failed", "cancelled"],
remind_at__lte=cutoff # ← Should check created_at for retried items!
)Impact: Reminders created 6 months ago that keep failing will never be cleaned up because their Fix: Add 4. ✅ Inconsistent user/channel detection - CONFIRMED BUGLocation: The code uses string prefix checks instead of the if not options["dry_run"] and reminder.target_id and reminder.target_id.startswith(("U", "W")):
exists, retry_after_exists = _user_exists(ws_token, reminder.target_id)The Fix: Use 5. ✅ Overzealous huddle cancellation - CONFIRMED BUGLocation: Temporary API failures cause permanent huddle cancellation: exists, retry_after_exists = _user_exists(ws_token, h.creator_id)
if not exists and not retry_after_exists:
h.status = "cancelled" # ← Permanent cancellation!
h.save(update_fields=["status"])Impact: Network hiccup or rate limit → legitimate huddle permanently cancelled. Fix: Only cancel if 6. ✅ Duplicate status transition logic - CONFIRMED ISSUELocation: Models define methods, scheduler bypasses them Models have proper methods: # website/models.py
def cancel(self):
updated_rows = self.__class__.objects.filter(pk=self.pk, status="scheduled").update(status="cancelled")
...
def start(self): ...
def complete(self): ...Scheduler bypasses them: # process_slack_reminders_and_huddles.py
h.status = "cancelled" # ← Direct field update
h.save(update_fields=["status"])Fix: Use model methods consistently: 🟢 Not Issues (Working As Intended)7. ❌ Message escaping - NOT A BUGThe HTML entity escaping is correct for Slack! Slack's documentation states "There are three characters you must convert to HTML entities and only three: &, <, and >" Slack uses these as control characters for mentions ( 8. ❌ N+1 query patterns - NOT A BUG (Already optimized)The # Line 3285
options = poll.options.annotate(votes_count=Count("votes"))This is the correct optimization. The 🟡 Minor Issues (Non-blocking)9. 🟡 Token security - BASIC BUT ADEQUATEToken sanitization exists: # Line 20-21
def _slack_headers(token: str):
sanitized_token = token.replace("\r", "").replace("\n", "")No direct token logging found. Current approach is basic but adequate. Could enhance with:
